New Mission for Sandy Hook Teacher Kaitlin Roig

Roig said she hopes it will create a ripple effect of kindness. Teachers can go to the site to post messages about classrooms in need. It can be anything from a cupcake to an iPad. The class that receives the help, helps another. So it continues, on and on, and on.

"When we're able to care for one another freely and learn that it's better to give than to receive -- and to truly learn that," Roig said.

The morning of the tragedy, Roig recalled, she took a picture of the sunrise over the water, later realizing that could very well have been her last morning. That has served as a reminder for her to enjoy every single day.

Some mornings, she takes another photo.

"Yes, not every morning," Roig said. "But no, I have. It's just so beautiful. It's just so important to take that moment. You just don't know."
